The invention concerns a chamber (1) divided into two zones (11, 12) for preservation at different temperature, separated by a vertical mobile thermal barrier (10), capable of sliding horizontally and enabling said zones (11, 12) to exhibit modifiable dimensions as required. The meal trays (4) comprise, on opposite edges, notches (7) adapted to receive a removable insulating partition (8, 9) separating the meals (13) to be served hot from those to be served cold and whereof the position can be modified to correspond with that of the thermal barrier (10). Vertical sheaths (21) enable, by means of turbines, to circulate warm or cool air, through orifices (22). A valve (23) prevents the air in sheaths (21) from passing through the evaporator (18). Electric resistors (16) with fins are arranged opposite or beneath the meal trays (4). A refrigerating compressor (20, 20′), provided in a lower casing (2) or an upper casing (3), for cool air diffusion and circulation, feed the evaporator (18).
A device for the preservation and reheating of tray meals with modular hot and cold regions, which comprises a thermally insulated, stationary or movable, chamber comprising a lower box and an upper box separated by a space able to contain several stacked tray meals and having, passing through these tray meals, two independent circuits, namely a cooling circuit and a reheating or cooling/reheating circuit, wherein the chamber is divided into two regions separated by a vertical movable thermal barrier which can slide horizontally and allows said regions to be at different temperatures and to have dimensions that can be modified according to requirements, the tray meals having, on two opposed edges, notches capable of housing a removable insulating partition separating dishes to be served hot from those to be served cold and a position of said insulating partition may be modified to correspond with that of the thermal barrier.
